Chloroform was in bottle from Caylee site

ORLANDO, Fla., Nov. 6 (UPI) -- FBI lab technicians said traces of chloroform were inside a bottle and a syringe found near the Florida site where Caylee Marie Anthony's remains were found.

The Orlando (Fla.) Sentinel said the discovery of the chloroform inside the syringe and sports drink bottle is detailed in more than 2,100 pages of documents released by the State Attorney's Office Friday.

FBI lab technicians said in a report that a plastic syringe was found inside of a plastic bag labeled "Disposable Syringe Kit." The bag was found inside of the drink bottle, the "Summary of results" report states.

The remains of 2-year-old Caylee were found in Orange County, Fla., in December 2008, months after her mother, Casey Anthony, reported her missing.

Anthony, 23, is facing first-degree murder charges for her daughter's death. Prosecutors are seeking the death penalty for Anthony if she is convicted.

The Sentinel said authorities were unable to determine a cause of death for the toddler.
